PURPOSE: To enable control of a plurality of dampers for pressure regulation by using one fuzzy inference means, by connecting a plurality of input processing means and output processing means to the fuzzy inference means by switching them over sequentially.
CONSTITUTION: A plurality of input processing parts 65a to 65c and output processing parts 67a to 67c are connected to a fuzzy inference part 63 by switching them over sequentially by a switching part 69. Based on a differential pressure deviation value Pf from the input processing parts 65a to 65c connected to the fuzzy inference part 63, a modified amount ΔM of the opening of dampers 57a to 57c for pressure regulation is determined by the fuzzy inference part 63 and this modified amount ΔM of the opening is outputted to the output processing parts 67a to 67c connected to the fuzzy inference part 63. By these output processing parts 67a to 67c, the opening of the dampers 57a to 57c for pressure regulation is computed and outputted. According to this constitution, a plurality of dampers 57a to 57c for pressure regulation can be controlled easily by using one fuzzy inference part 63.
